基于SASL_SSL的Kafka Java客户端，忽略信任库的配置并采用默认证书

Question

我正在尝试使用默认证书进行握手的使用者，而忽略了Config中定义的证书，出了什么问题？

尝试使用邮件时，它正在使用默认证书并引发SSL握手错误。

    public class Consumer {

    final KafkaConsumer<String,String> mConsumer;
    final Logger mLogger = LoggerFactory.getLogger(Consumer.class);

    private Properties consumerProperties(String bootstrapServer,String username, String password,String certPasswd) {
        //String serializer = StringSerializer.class.getName();
        String serializer = StringSerializer.class.getName();
        String deserializer = StringDeserializer.class.getName();
        String jaasTemplate = "org.apache.kafka.common.security.plain.PlainLoginModule required username=\"%s\" password=\"%s\";";
        String jaasCfg = String.format(jaasTemplate, username, password);
        Properties props = new Properties();
        props.setProperty(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,bootstrapServer);
        props.setProperty(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, serializer);
        props.setProperty(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,serializer);
        props.setProperty("security.inter.broker.protocol", "SASL_SSL");
        props.setProperty("bootstrap.servers", bootstrapServer);
        props.setProperty("group.id", username + "-nprod-consumer");
        //props.setProperty("enable.auto.commit", "true");
        props.setProperty("auto.commit.interval.ms", "1000");
        props.setProperty("auto.offset.reset", "earliest");
        props.setProperty("session.timeout.ms", "30000");
        props.setProperty("key.deserializer", deserializer);
        props.setProperty("value.deserializer", deserializer);
        props.setProperty("key.serializer", serializer);
        props.setProperty("value.serializer", serializer);
        props.setProperty("security.protocol", "SASL_SSL");
        props.setProperty("sasl.mechanism", "PLAIN");
        props.setProperty("ssl.keystore.location","client.keystore.jks");
        props.setProperty("ssl.keystore.password",certPasswd);
        props.setProperty("ssl.key.password",certPasswd);
        props.setProperty("ssl.enabled.protocols","TLSv1.2,TLSv1.1,TLSv1");
        props.setProperty("ssl.client.auth","required");
        props.setProperty("ssl.truststore.location","client.truststore.jks");
        props.setProperty("ssl.truststore.password",certPasswd);
        props.setProperty("sasl.jaas.config", jaasCfg);
        return props;
    }

    Consumer(String bootstrapServer,String username, String password,String certPassword) {
        Properties props = consumerProperties(bootstrapServer,username,password,certPassword);
        mConsumer= new KafkaConsumer<>(props);
        mLogger.info("Consumer Initialized");
    }

    void read(String topic) throws ExecutionException, InterruptedException {
        mConsumer.subscribe(Arrays.asList(topic));
        while (true) {
            ConsumerRecords<String, String> records = mConsumer.poll(1000);
            for (ConsumerRecord<String, String> record : records) {
                System.out.printf("%s [%d] offset=%d, key=%s, value=\"%s\"\n",
                                  record.topic(), record.partition(),
                                  record.offset(), record.key(), record.value());
            }
        }
    }
    void close(){
        mLogger.info("Closing Consumer");
        mConsumer.close();
    }
}

请提出建议，我如何才能忽略默认证书，并为用户强制执行在configs中定义的证书。
